What list-pin-read does on Nostr Bray
AI agents call list-pin-read to retrieve information from Nostr Bray without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Why list-pin-read is rated Low
This tool queries and retrieves a user's pinned events from their Nostr profile without creating, modifying, or deleting any data. It is a straightforward read operation with minimal security risk—the worst outcome is information disclosure of the user's own pinned content.
From the tool's definition Tool name contains 'read' and description states 'Read your pinned events list'. The action retrieves existing data (NIP-51 pinned events) with no modification or side effects.
